Patented Sept. 23, 1930 UNITED STATES PATENT OFFICE JOHN J. DONOVAN ANDESMOND F. WILEY, F OAKLAND, CALIFORNIA AWNING-TYPE WINDOW Applicationfiled August 1, 1928. Serial No. 296,676.

This invention relates to awning type windows.

Hitherto, awning type windows have been manufactured which include aseries of swinging sashes pivotally and slidably mounted in a frame foroperation. The pivotal and slidin connections include a pair of fulcrumlin s for each sash which are pivoted intermediate the ends of thesashes and to the frame, and sliding shoes fitted to the upper ends ofthe sashes and slidably engaging trackways formed in the jambs of theframe. In order that the sashes may be independently operated the upperends of the sashes are connected together by a connecting memberarranged vertically intermediate the sashes and the jamb. Thisconnecting member is capable of operation to disconnect the sashes sothat they may be operated independently. As the fulcrum links and theconnecting member are arranged between the sashes and.the jamb and asthe connecting member requires a certain amount of clearance foroperation, it was necessary that the frame be of considerable depth. Inwood construction thereis ample space for these elements and suchconstrue t-ion results in an ideal arrangement for windows of this typebut when endeavoring to .30 convert these windows into all steelconstruction the steel frame must be of a design substantially the samein dimensions as the wood type frame. Therefore, these all steel windowswere very expensive to manufacture,

extremely heavy and not at all suited for their purpose.

It is the principal object of the present invention to provide acomparatively inexpensive awning type window operating as above 4" setforth which canbe incorporated into a steel frame of simple design andof minimum dimensions.

One form which the invention may assume is exemplified in the followingdescription and illustrated by way of example in the accompanyingdrawings, in which:

Fig. 9 is a fragmentary View in perspective of one of the travellingbars showing the recess therein.

Fig. 10 is a perspective view of one of the shoes carried by the lowersash.

Referring more particularly to the accompanying drawings 10 indicates awindow frame of suitable dimensions and construction. This frame isformed of bars of channeled material as illustrated in the drawings.This material is of a standard shape and stock and is principally usedin the manufacture of window frames for factories, schools and otherbuildings using metallic trim. Windows having frames constructed of thismaterial are durable, comparatively inexpensive and have a maximumarea,of glass.

The frame 10 is formed with two sash openings 11 within which sashes-12and 14 are mounted for swinging movement in a vertical plane. Each sashis connected with the frame by a pair of fulcrum links 15. These fulcrumlinks are disposed exteriorl of the window as illustrated and are pivota1y connected at their lower ends to lugs 16 permanently fixed on theexterior face of the jambs of the frame.

It will be noticed that the links 15 of each intermediate the ends ofthe latter.

of and in horizontal alignment. The upper ends of the fulcrum links 15are pivotally connected to the sides of the sash at a p%ilrlit e pointof connection between the links 15 and the sash is spaced further fromthe face of the frame 10 than the point of connection between the linksand the' frame. This arrangement of the pivotal points of the fulcrumlinks causes the sashes to tightly close and remain so when the sashesare drawn to closed position;

The upper end of each sash is pivotally and slidably connected to thejambs of the frame so that the sashes will pivot about their upper endsin a vertical plane as illustrated in Fig. 1 of the drawings. Includedin the pivotal connections between the sashes and the ambs of the frameis a pair of travelling bars 17 disposedone adjacent each jamb andnested within the channeled portion thereof intermediate the sash andthe jamb. The upper sash is fitted at its top rail with a pair ofoutwardly projecting connectors 18 which are constantly urged outwardlyby springs 19.

Theconnectors 18 and springs 19 are housed within barrels 2O suitablysecured to the upper rail of the sash. These connectors 18 projectbeyond the sides of the sash and engage sockets 21 formed in the innersurfaces of the travelling bars 17. The connection between the uppersash and these travelling bars forms a pivotal and sliding connectionbetween the upper end of the upper sash and the jambs of the frame,enablin operation of the upper sash as the travelling bars 17 mareciprocate in the channeled jambs.

t is desired to point out that the springs 19 which tend to press theconnectors 18 outwardly cause a certain amount of friction between thetravelling bars 17 and the jambs of the frame so that the sashes willremain in any set position, but may be operated easily.

The connection between the top rail of the.

lower sash and the travelling bars 17 is similar to that just describedwith 'theexception that sliding shoes 22 are arranged on the connectors18 intermediate the travelling bars 17 and the sides of the sash. Alsothe connectors 18 of the lower sash are connected by means of operatingrods 23 to an operating member 24 which is capable of operation towithdraw the connectors 18 from engagement with the sockets 21 in thetravelling bars 17 The movement of the connectors 18 is limited,however, so that they cannot be withdrawn from the shoes 22. Thus, whenthe connectors 18 are withdrawn from engagement with the sockets 21 inthe travelling bars 17 a sliding and pivotal connection will beestablished between the upper end of the lower sash and the lower endsof the travelling bars .17, so that the sashes may be operatedindependently of each other;

It will be noticed that the travelling bars 17 extend a considerabledistance below the point of connection between them and the lower sashso that ample guide means will be provided for the lower sash when it isoperated independently of the upper one.

In operation of the window, it is constructed and assembled asillustrated in the drawings with both sashes operatively connected tothe travelling bars 17. To open the windows it is only necessary tograsp the lower rail of either of them and press outwardly, causing thewindows to open as illsutrated in Fig. 1. As the travelling bars 17 bearagainst the jambs with a certain amount of friction, the windows willremain in any set position Whether opened or closed.

The disposition of the pivotal points of the fulcrum links 15 upon whichthe sashes are suspended will cause the sashes to tightly close whenthey are drawn to this position.

To operate the sashes independently it is only necessary to operate themember 24 to withdraw the connectors 18 from engagement with the sockets21 in the travelling bars 17 Either sash may then be operatedindependently of the other. As soon as the operating member 24 isreleased and the connectors 18 of the lower sash aligned or registeredwith the sockets 21 on the travelling bars 17 they will re-engage thesesockets and connect the sashes together.

It is desired to point out here that although two sashes are shown inthe present instance, it should be understood that. a greater number ofsashes may be arranged in a single frame if desired and still beoperated by means of the mechanism here disclosed.

.Particular attention is directed to the fact that the depth of theframe is no greater than the depth of the sash rails themselves, andthat the operating mechanism with the exception of the fulcrum links 15is all concealed, when the sashes are closed.

Also. the frame is constructed of standard material and the operatingmechanism is so designed that it will be inexpensive to construct,enabling the window to be produced at a figure far less than awning typewindows of present day construction.

While the preferred form of the invention has been here disclosed, it isto be understood that various changes may be made in its construction bythose skilled in the art without departing from the spirit of theinvention as defined in the appended claims.
